>Hi, I run a mailing list using Macjordomo with SIMS as my mailer. For one user on the list, my outgoing messages get rejected as having an unverified sender address. Although this is supposedly temporary, the user does not seem to get messages in a timely fashion. Her ISP says that it a problem with SIMS. Is there something I can do to fix this on my end?

Does your SIMS have an account named: mailinglist-request? It doesn't look like it. It sounds like their server tries to establish a connection to send to mailinglist-request@montague.lin.msu.edu before accepting mail from that sender. It's an extreme anti-spam measure.
